fix(orchestrator): hub gate view reads recorded parents through gates.opened

W5 moved recorded parents into a journal that gates.opened() loads into a TEMP table; the W3 hub opened gates.db raw, so parents_of() raised and the gate view stayed empty. opened() and journal() take the kept directory explicitly (CLI: watch.KEPT, hub: its /kept mount), opened() closes the connection when setup raises, and the W3 tests use opened() plus a test for a parent from the kept journal.

🎯 Fix: 95 %
💥 Break: 3 %
💸 Cost: 100 %
⏱️ Time: 100 %
🛡️ Security: 100 %
🏆 Score: 92
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %
